Default Regex Problem

There is a problem with the code in the ProcessSpecialTags function in ForumsBusiness Helper.css.

If you use 2 or more of the same tag in a paragraph, the Regex.Replace function will treat everything in between the first opening tag and the last closing tag as one expression pattern. For instance, if you were using two I tags, then everything from the first opening tag to the second closing tag would appear in italics and the first closing tag and the second opening tag would be included in the text.

I actually ran into this issue on a major website recently. I couldn't include 2 or more links in the same sentence unless I put each one on a different line. Can anyone suggest a fix?

I just found this problem too! There must be a way around this, just not sure how yet.
The textbox to post messages on this forum implements this correctly.

Hi Claude,
        I just figured out how to get more than one .. tag to render. Here is my implementation:

public string ProcessSpecialTags(string stringToTransform)

            StringBuilder formattedSource = new StringBuilder();
            string[] table = new string[2];

            table[0] = "<b>";
            table[1] = "</b>";
            MatchCollection matchs;
            // Look for code
            matchs = Regex.Matches(stringToTransform, "\\[b\\](?<bold>(.|\\n)*?)\\[/b\\]", RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.Compiled);

            foreach (Match match in matchs)

                // Get the formatted source code

                // Update the main string
                stringToTransform = stringToTransform.Replace(match.ToString(), formattedSource.ToString());
                formattedSource.Remove( 0, formattedSource.Length );

            return stringToTransform;


If you need real world example of this, check out the new ASP.NET Forums Beta RC2 application, in the Components solution, goto the Components folder, and then to the Transforms.cs file. Then goto line 403 or search for: SourceCodeMarkup(string stringToTransform)

My example above was adapted from the ASP.NET Forums code.

Hope this helps everyone,
